Abstract (en)
[origin: EP1101640A2] A casing (11) has air inlet and outlet openings which are connected through an air flow passage defined in the casing. The casing has a bottom surface in the vicinity of the air inlet opening. An evaporator (13) is arranged in the air flow passage. A heater (15) is arranged in the air flow passage at a position downstream of the evaporator (13). An air flow control door is arranged in the air flow passage for controlling a ratio between an air amount flowing in a heater-bypassing passage which extends from the evaporator to the air outlet opening bypassing the heater and an air amount flowing in a heater-passing passage which extends from the evaporator to the air outlet opening through the heater. A water guide groove is provided at the bottom surface of the casing at a position opposite to the position where the air inlet opening is provided. A drain pipe (23) is held by the casing and connected to the water guide groove. A plurality of water backflow obstruction projections are formed on the bottom surface in an area defined between the water guide groove and the air inlet opening. Each projection is shaped and oriented so as to obstruct a flow of water in a direction from the water guide groove toward the air inlet opening. <IMAGE>
